While "trolling" some of the deep, dark secrets of crossover mods past, I came across this (partial) post, (attributed to DeanG and/or John Albright) that sounds good, and am wondering if it still holds true for both the E and E2 networks.  Also, here is the closest resistor I found, seems to be the proper values...   http://www.parts-express.com/15-ohm-10w-resistor-wire-wound-5-tolerance--016-15   (or is there a "better" resistor, or different type that should be used?)
